The COSMO COS-2413ORM1SS is a 24-inch over-the-range microwave that combines a two-tone black and stainless steel look with 1,000 W of power and a 13.6-inch turntable, all at $308.99. With 2,413 units bought last month and 486 reviews at 4.4 stars, it's clearly a category leader in the compact OTR segment.
Compact or galley kitchens with a 24-inch range opening that also want an attractive two-tone finish. The volume of purchases makes this a low-risk pick for an underdocumented niche.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The COS-2413ORM1SS measures 16.1 x 23.8 x 17 inches and weighs 57.3 lb. The 13.6-inch turntable is notably generous for a 24-inch unit, handling most standard plates and bowls comfortably. Ten power levels and 1,000 W output place it squarely in the standard performance tier for OTR microwaves. Controls are touchscreen-based with a clean, modern layout.
The visual design sets it apart from most compact OTR units. The black and stainless combination reads as more intentional than budget appliances in this size class, making it a practical choice for design-conscious kitchens that can't use a 30-inch unit.
The purchase numbers tell a clear story: 2,413 units bought last month is an unusually high figure for a 24-inch OTR microwave, suggesting it's become the go-to option for this niche. Combined with 486 reviews averaging 4.4 stars, buyers appear to be consistently satisfied. The $309 price is reasonable for the 24-inch category, where comparable options from Haier and others cost more for similar specs.

What buyers say
The combination of 486 reviews at 4.4 stars and over 2,400 units sold last month points to an unusually satisfied buyer base for a niche appliance category. Purchasers seem to primarily value the 24-inch sizing and the visual design. No dominant negative themes appear given the high satisfaction rate.
How does the COSMO compare to the Haier HMV1472BHS in 24-inch OTR?
Both are 24-inch OTR units at 1,000 W. The COSMO is about $165 less, has a larger review base with a higher star rating, and sells in far greater volume. The Haier offers black stainless steel as a single finish; the COSMO uses a two-tone black and stainless design.
Will the COS-2413ORM1SS work with a recirculating vent configuration?
Ventilation configuration details are not available in the listed specs. Most OTR microwaves support both recirculating and external-duct setups, confirm with COSMO's documentation or your installer before purchasing.
Is 1.34 cu ft interior enough for everyday use?
For one or two people reheating single plates, it's workable. For families regularly heating large dishes, the interior fills up quickly. A standard 30-inch OTR with 1.6-1.9 cu ft will serve larger households better if cabinet space allows.
